We're not hiring a dj because of budget issues. We're going the iPod/iTunes laptop route. I found a Portable PA with an iPod hookup that blasts music up to 150 yards away. I know it's not a full on system, but do you think it will be enough to provide background music for up to 90 people (probably more like 60-70)? Are you having an iPod reception? Our venue doesn't come with a system so I'm trying to figure out the best way possible to get music played for people to enjoy.
